Tesla Holiday Update: New UI for Model 3 and Y, Light Show, blind spot camera improvements & more
Just a few days before Christmas, Tesla is kicking off the holidays with a bang. This year’s Holiday Update includes a few fun surprises for Tesla owners, including new games and a few other fun features.
Teslascope, a Tesla software update tracker service, has shared that the 2021.44.25 update is being rolled out to employees for now, with a wide release following in the lead up to Christmas. Reports shared online suggest that the update works very smoothly on vehicles like the Model 3 and Model Y, however.
New Features
First off is the Light Show, which enables Tesla vehicles to dance to a choreographed light show any time of the year. The feature was a signature trick of the Model X, so it is pretty interesting that Tesla is now rolling it out to the other vehicles in its lineup. The Light Show feature can be accessed through the Toybox.
In its Holiday Update, Tesla also introduced the Customizable App Launcher, allowing owners to customize the menu bar in their infotainment systems. This should go perfectly hand-in-hand with the Model 3 and Model Y’s update UI, which now matches the interface of the Model S Plaid and new Model X that were rolled out this year.
“Drag and drop your favorite apps to any position along the bottom menu bar for easy access. To customize your menu bar, hold any icon and then drag to reorder. To adjust climate controls such as heated seats and defrost, tap on the temperature or swipe up from the bottom of the screen,” the update’s Release Notes read.
Feature Improvements
As with any update, Tesla improved a few key features, including vehicle controls, blind spot monitoring, and Waypoints.
Simplified Controls makes it easier for Tesla owners to focus on navigation, media, and the most common primary controls. The improvement should make accessing features in the infotainment system easier, so driving or operating a Tesla may be more convenient and perhaps even safer.
The Blind Spot Camera feature is probably one of the best improvements in the Tesla Holiday update, as it provides vehicles with a video feed showing their blind spot when a turn signal is activated. “You can now automatically see a live camera view of your blind spot whenever you activate the turn signal,” the Release Notes for the feature read.
The Blind Spot Camera feature will most likely improve the safety of Tesla’s vehicles. Tap Controls>Autopilot>Automatic Blind Spot Camera to enable the feature.
Tesla also made trips easier with Edit Waypoints. The navigation improvements will probably be quite useful to families taking trips this holiday. The feature allows drivers to reorder or add multiple destinations to their route. Edit Waypoints will update the arrival times for each change on the route. “To add a stop, or edit a trip, initiate a navigation route, and tap the more options button not he turn list,” wrote Tesla on the Edit Waypoints Release Notes.
New Arcade Improvements
Being a Holiday Update, 2021.44.25 is rife with a number of improvements for Tesla Theater and Tesla Arcade. Access to a popular social media platform has also been enabled.
First up is Sonic the Hedgehog, which Elon Musk himself announced on Twitter recently. Multiplayer support for The Battle for Polytopia has also been enabled, which should make in-car gaming sessions even more fun.
Sudoku has also been added to the Tesla Arcade, complete with a mode that includes a smart hint system for beginners. Also, the popular social media app TikTok is now accessible to Teslas.
Other Improvements
Update 2021.44.25 is not all fun and games. Tesla included some Cold Weather Improvements to its Holiday Update, too. Preconditioning the cabin from the Tesla Mobile App when the battery is at a lower state of charge is now enabled. First row seat heaters can now automatically regulate seat temperatures based on the cabin’s environment and control set temperature.
Managing dashcam clips is also easier, as videos can now be deleted directly from the infotainment system. Themes for the infotainment system have been rolled out, too. For instance, Dark Mode is now available for Tesla displays. Dark Mode may be a simple update, but it could make vehicles safer, as a darker display reduced the chance of screen glare for the driver.

Elon Musk confirms xAI’s purchase of five 380 MW natural gas turbines
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI, Elon Musk’s artificial intelligence startup, has purchased five additional 380 MW natural gas turbines from South Korea’s Doosan Enerbility to power its growing supercomputer clusters.
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.

A $20 billion Series E round
As noted by the artificial intelligence startup in its post, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others.
Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.
As xAI stated, “This financing will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products reaching billions of users, and fuel groundbreaking research advancing xAI’s core mission: Understanding the Universe.”
xAI’s core mission
Th Series E funding builds on xAI’s previous rounds, powering Grok advancements and massive compute expansions like the Memphis supercluster. The upsized demand reflects growing recognition of xAI’s potential in frontier AI.
xAI also highlighted several of its breakthroughs in 2025, from the buildout of Colossus I and II, which ended with over 1 million H100 GPU equivalents, and the rollout of the Grok 4 Series, Grok Voice, and Grok Imagine, among others. The company also confirmed that work is already underway to train the flagship large language model’s next iteration, Grok 5.
“Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote.
Tesla (NASDAQ: TSLA) stock received a price target update from Pierre Ferragu of Wall Street firm New Street Research, citing the company’s growing lead in self-driving and autonomy.
On Tuesday, Ferragu bumped his price target from $520 to $600, stating that the consensus from the Consumer Electronics Show in Las Vegas was that Tesla’s lead in autonomy has been sustained, is growing, and sits at a multiple-year lead over its competitors.
CES 2026 validates Tesla’s FSD strategy, but there’s a big lag for rivals: analyst
“The signal from Vegas is loud and clear,” the analyst writes. “The industry isn’t catching up to Tesla; it is actively validating Tesla’s strategy…just with a 12-year lag.”
The note shows that the company’s prowess in vehicle autonomy is being solidified by lagging competitors that claim to have the best method. The only problem is that Tesla’s Vision-based approach, which it adopted back in 2022 with the Model 3 and Model Y initially, has been proven to be more effective than competitors’ approach, which utilizes other technology, such as LiDAR and sensors.
Currently, Tesla shares are sitting at around $433, as the company’s stock price closed at $432.96 on Tuesday afternoon.
Ferragu’s consensus on Tesla shares echoes that of other Wall Street analysts who are bullish on the company’s stock and position within the AI, autonomy, and robotics sector.
Dan Ives of Wedbush wrote in a note in mid-December that he anticipates Tesla having a massive 2026, and could reach a $3 trillion valuation this year, especially with the “AI chapter” taking hold of the narrative at the company.
Ives also said that the big step in the right direction for Tesla will be initiating production of the Cybercab, as well as expanding on the Robotaxi program through the next 12 months:
“…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
Tesla analyst breaks down delivery report: ‘A step in the right direction’
Tesla has transitioned from an automaker to a full-fledged AI company, and its Robotaxi and Cybercab programs, fueled by the Full Self-Driving suite, are leading the charge moving forward. In 2026, there are major goals the company has outlined. The first is removing Safety Drivers from vehicles in Austin, Texas, one of the areas where it operates a ride-hailing service within the U.S.
Ultimately, Tesla will aim to launch a Level 5 autonomy suite to the public in the coming years.
